Which step shows the result of applying the subtraction property of equality? One-fourth (12 x + 8) + 4 = 3 Step Solution 1 3 x
luda_lava [24]

Answer:

Step-by-step explanation:

Given the equation 1/4 (12 x + 8) + 4 = 3, to fnd the result of the equation, the following steps must be followed.

Step 1: Expand the bracket at the left hand side of the equation using the distributive property.

1/4 (12 x + 8) + 4 = 3

\frac{1}{4} (12x)+\frac{1}{4}(8) + 4 = 3\\ 3x+2+4 = 3\\3x+6=3

Step 2: Subtract 6 from both sides of the equation

3x+6-6 = 3-6\\3x  =-3\\x = \frac{-3}{3}\\ x = -1

Isaac keeps track of the miles per gallon his car gets per week. He has accumulated the following data:
ipn [44]

we know that

A <u>geometric sequence</u> is a sequence of numbers in which the ratio between consecutive terms is constant

so

Let

a1=24 \ a2=24.48\ a3=24.97\ a4=25.47

\frac{a2}{a1} = \frac{24.48}{24}= 1.02

a2=a1*1.02

\frac{a3}{a2} = \frac{24.97}{24.48}= 1.02

a3=a2*1.02

\frac{a4}{a3} = \frac{25.47}{24.97}= 1.02

a4=a3*1.02

therefore

The common ratio is equal to 1.02

<u>the answer is</u>

The common ratio is 1.02

Santiago hopes to buy a 4 horse trailer for about $12000. Describe all the numbers that when rounded to the nearest hundred are
jok3333 [9.3K]
To round a number to the nearest hundred, we count two places to the left of the decimal point, or from the last digit if the number is a whole number.

If the second digit from the last digit is upto 5, we add 1 to the preceding digit and we complete the last two numbers with zeros.

Therefore, any number from 11,950 to 12,049, will result to 12,000 when rounded to the nearest hundred.
